The iPhone 5s is in short supply right now, with Apple struggling currently to ship enough units to meet the insatiable demand. But if you want the look of the Cupertino’s latest and greatest handset without paying the hefty sums Apple is charging, you may be interested in the much cheaper option of an “Upgrade Kit,” which essentially allows you to turn your iPhone 5 into an “iPhone 5s” of any color variant.

Of course, the Upgrade Kit doesn’t actually upgrade any of your internal hardware, so once you’ve applied it, you’re still left with an iPhone 5 in a 5s shell. With that said, the conversion package does look rather plausible, and if you were more interested by the new Space Gray or Gold color configurations than the fingerprint sensor, improved camera or enhanced, 64-bit processor, then the Upgrade Kit is your perfect go-between.

With even the 16GB iPhone 5s costing several hundred dollars unsubsidized, it’s certainly not cheap, but since the Upgrade Kit costs just £14.99 from Mobile Fun (around $24US), you can give your iPhone 5 a fresh makeover.

The Gold version of the iPhone 5s is currently commanding up to $1800 on eBay, but with Mobile Fun catering to the Silver, Space Gray and Gold colors, you can get that sought-after look without having to pay extortionate sums of money.

The real iPhone 5s, which is sold out almost everywhere you look right now, is reckoned by many to be the biggest upgrade to the iPhone range in many generations, but while the features alone are pretty impressive, it is the gold rush that has really gotten people talking about Apple’s most recent export.

Having released alongside the iPhone 5c, which itself offers a plethora of colors, the iPhone 5s shifted several million units during its first three days, and although Apple Retail Stores are gradually receiving more batches of devices, those having ordered online are unlikely to see their iPhone 5s until October.

So, with all this waiting and money changing hands, you can essentially avoid both by “upgrading” your iPhone 5 to suit the current generation thanks to Mobile Fun. And hey, judging by the images below, the result is pretty convincing!
